Diversity branch delay alignment in radio base station

A base station included in a radio access network of a telecommunications system and comprising:

• two diversity antennas for a cell/carrier utilized in a sector served by the base station from which are respectively obtained two branches of a radio link signal transmitted between the base station and a user equipment unit;
• two branches of signal processing hardware at the base station which respectively process the two branches of the radio link signal either before or after transmission between the user equipment unit and the base station;
• and
• a rake receiver which measures a delay difference between the two processed branches of the radio link signal.

A radio access network of a telecommunications system comprising:

• a base station having two diversity antennas for a cell/carrier utilized in a sector served by the base station;
• a test user equipment unit situated essentially equidistantly with respect to the two diversity antennas, two branches of a radio link signal received from the test user equipment unit being obtained respectively from the two diversity branches;
• the base station further comprising:
• two branches of signal processing hardware which respectively process the two branches of the radio link signal;
• a rake receiver which measures a delay difference between the two branches of the radio link signal.
